ANTISKID FOR WHEELS.

Specification of Letters Patent.

tection of cables. ropes and chains in order to protect them both from wear and from being cut 1n two, while at the same time preserving the flexibility of the same. This 'armor is particularly designed for use on the cross members of the antiskids both on trucks and automobiles.

The armor consists essentially of comparatively short tubula members loosely mounted upon the cable, rope or chain to be shielded and rotative thereon.

In the drawings forming part of this specification, Figure 1 is a transverse section of a Wheel rim and tire showing my improvements ap 'plnid thereto. Fig. 2 is a face view of the key in iich I prefer to use for the attachment of one end of a cross member. Fig. 3 is a pers 'ective view of a. portion of the bolt for theIZltttachment of the other end of the cross me ber. Fig. 4 is a perspective view of one of the armor fasteners. Fig. 5 is a perspective view of the anchor plate to which a cross member is terminally attached.

Fig. 6 is a sectional view of a portion of the anchor pla showing an attaching bolt held thereby. ig. 7 is a longitudinal section of one of the tubular elements which compose the armor of the cross members.

In Fig. 1, the reference numeral 1 designates the felly, of a vehicle wheel, the one selected for illustration being of the twintire type; 2 is one of the spokes thereof; 3 the metal rims, and t the rubber tires.

I am showing but a single crossmember. since all which may be used upon a wheel are substantially alike. The tensile element of this member is preferably a slender wire cable 5 having its ends suitably attached to 2 and passing about the tire 4 to conform generally to the face of the tire. Upon this wire cable or rope is strung a series of wear-resisting armor elements or sleeves 6, preferably composed of hardened steel. These sleeves are preferably formed as shown with male and female ends for the purpose of preventing gaps between them, especially where the cross member rounds a sharp curve, and also to enable each sleeve to partially support its immediate neighbors.

These sleeves (5 are shown more in detail in Fig. 7, where 5) indicates the convex or ball end, and 10, the concave or socket end.

After a suflicieut number'of the sleeves have been strung upon the wire rope 5, an anchor sleeve 1). 1s applied at each cud'and fixed thereon by. a set screw 13. To better insure the grip on the rope, the sleeves are each formed with a slot it opposite the set screw, as shown in Fig. l. The wire rope being partially forced into such slots by the pressure of the set screws, the anchor sleeves 12 are firmly held in place.

The means which I have shown for attaching the cross members to the wheel oomprise an anchor plate 1. suitably fastened to the wheel, as by means of bolts and a plate 16 by which it is clamped to one of the spokes 2, and terminal attaching devices for engaging said plate. The attaching device for one end of the wire rope consists of a key 17 thin enough to be inserted in the slot 19, and having oppositely disposed notches 20 by means of which to retain the key in the slot when turned to lie in a plane transverse to the slot.

At an end of the key is a head 21 having a transverse slot 22 therein fitted to receive a threaded staple 22 -5. The end of the .wire rope having been inserted within the staple, as shown in Fig. 1. and the nut ll on the leg or legs of the staple forcibly turned to press the l'ope against the head 21. said rope end is firmly fastened in place. To render this grip even stronger. the staple is formed with a lug 25 adapted to be forced into the rope and to make the hold upon the latter See Fig. 3.
